It would seem then that the determining factor would be leg turnover coupled with the endurance to carry that rate of turnover for 800 meters. How's that? Of course it would help to not carry 207 pounds on a 5' 9" frame.

Maybe 157 tops._________________"Find the level of intolerance you can tolerate and stay there." David Horton

Krummenacker's pretty tall -- I would guess around 6'2". On the other hand, 5'8" is towering by Kenyan standards. It's a combination of a lot of things, as is the case for any event. Stride length is almost as big of a factor as turnover, and then you get into all the aerobic/anaerobic aspects that are far more important than physique.

Just look at the top women 800m runners. Mutola, Graf, and Holmes are built like tanks. You don't have to be a gazelle to run a fast half.

I find that one of the interesting things about the middle distance runners. The sprinters tend to be muscular and the 5K and up runners tend to be very thin. But in the 800-1500 you can find a relatively different group of body types.

You tend to see that happening again in the ultras, especially the 100 mile races. There are some traditional skinny runners but you also see a good representation at the front of runners with a good bit of muscle and size. Dean Karnazes and Jenny Capel are two good examples._________________"Find the level of intolerance you can tolerate and stay there." David Horton
